  • How to prepare a codebase for compiling on both Windows and Unix-based systems

    - by Max
    Hi! I am wondering about different solutions to easily compile my cross-platform application for both windows and unix. Right now I am using a makefile on Ubuntu, but before my codebase grows larger I'd like to perform the steps necessary to compile it on Windows, and then continue doing so regularly to see that it still works. I'd preferably not contaminate my SVN codebase repository with multiple "makefile" solutions, such as VC++ solutions and so on, I'd like a more automatic way. I tried using mingw with make for windows, but it seems my secondexpansion awesomeness doesn't work on the Windows version (or something like that). It wouldn't compile, and also complained about _winNT or something like that not being defined. How should I prepare my codebase for cross-platform easy compiling? Things like buildtools, perhaps autogenerate VS file from makefile, or something similar. Some preprocessor magic in a stdinc file perhaps? Thanks!

  • Why for only some actions must I call setTarget?

    - by Max Pierce
    For most actions, I just click and drag in InterfaceBuilder to "wire up" a call from some interface object to my code. For example, if I want to know when the user single-clicks a row in a table, I drag a connection from the table's action to my controller's action. But now let's consider the user double-clicking a row. If I want one of my actions to be called when this happens, I need to call not only -[NSTableView setDoubleAction] but also -[NSControl setTarget]. Why? To be clear, I am not asking why Interface Builder doesn't support setDoubleAction. All tools have limitations. I am trying to gain a greater understanding about how and why setTarget doesn't seem to be necessary unless and until I want setDoubleAction to work. Another way to ask this question would be: Why don't I need to do anything in Interface Builder to set the target of the table's (single-click) action?

  • How to define 'Attached property' as 'SelectedValuePath' in ComboBox?

    - by SpudCZ
    Hi, I have a problem with binding in ComboBox. I'd like to bind ComboBox items to ListView columns and as a selected value return value of attached property defined on the selected column. In example bellow you can see working sample that displays width of selected column. If you try to change SelectedValuePath in ComboBox into (loc:SampleBehavior.SampleValue) you get binding error: BindingExpression path error: '(u:SearchableListView.SearchMemberPath)' property not found on 'object' ''GridViewColumn' <Window x:Class="Problem_Sample1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:loc="clr-namespace:Problem_Sample1" WindowStartupLocation="CenterScreen" Title="Window1" Height="300" Width="300"> <DockPanel> <ComboBox DockPanel.Dock="Top" x:Name="combobox" ItemsSource="{Binding Path=View.Columns, ElementName=listview}" DisplayMemberPath="Header" SelectedValuePath="Width"> </ComboBox> <StatusBar DockPanel.Dock="Bottom"> <TextBlock> <TextBlock Text="Selected column (value): " /> <TextBlock Text="{Binding Path=SelectedValue, ElementName=combobox}" /> </TextBlock> </StatusBar> <ListView x:Name="listview"> <ListView.View> <GridView> <GridViewColumn Header="Name" Width="101" loc:SampleBehavior.SampleValue="201" /> <GridViewColumn Header="Surname" Width="102" loc:SampleBehavior.SampleValue="202" /> </GridView> </ListView.View> </ListView> </DockPanel> </Window>   SampleBehavior.cs using System.Windows; using System.Windows.Controls; namespace Problem_Sample1 { public static class SampleBehavior { public static readonly DependencyProperty SampleValueProperty = DependencyProperty.RegisterAttached( "SampleValue", typeof (int), typeof (SampleBehavior)); [AttachedPropertyBrowsableForType(typeof(GridViewColumn))] public static int GetSampleValue(GridViewColumn column) { return (int)column.GetValue(SampleValueProperty); } [AttachedPropertyBrowsableForType(typeof(GridViewColumn))] public static void SetSampleValue(GridViewColumn column, int value) { column.SetValue(SampleValueProperty, value); } } }   Thanks for any help or suggestion.

  • Running daemon through rsh

    - by Max
    I want to run program as daemon in remote machine in Unix. I have rsh connection and I want the program to be running after disconnection. Suppose I have two programs: util.cpp and forker.cpp. util.cpp is some utility, for our purpose let it be just infinite root. util.cpp int main() { while (true) {}; return 0; } forker.cpp takes some program and run it in separe process through fork() and execve(): forker.cpp #include <stdio.h> #include <errno.h> #include <stdlib.h> #include <unistd.h> int main(int argc, char** argv) { if (argc != 2) { printf("./a.out <program_to_fork>\n"); exit(1); } pid_t pid; if ((pid = fork()) < 0) { perror("fork error."); exit(1); } else if (!pid) { // Child. if (execve(argv[1], &(argv[1]), NULL) == -1) { perror("execve error."); exit(1); } } else { // Parent: do nothing. } return 0; } If I run: ./forker util forker is finished very quickly, and bash 'is not paused', and util is running as daemon. But if I run: scp forker remote_server://some_path/ scp program remote_server://some_path/ rsh remote_server 'cd /some_path; ./forker program' then it is all the same (i.e. at the remote_sever forker is finishing quickly, util is running) but my bash in local machine is paused. It is waiting for util stopping (I checked it. If util.cpp is returning than it is ok.), but I don't understand why?! There are two questions: 1) Why is it paused when I run it through rsh? I am sure that I chose some stupid way to run daemon. So 2) How to run some program as daemon in C/C++ in unix-like platforms. Tnx!

  • Automatically decorating every instance method in a class

    - by max
    I want to apply the same decorator to every method in a given class, other than those that start and end with __. It seems to me it should be doable using a class decorator. Are there any pitfalls to be aware of? Ideally, I'd also like to be able to: disable this mechanism for some methods by marking them with a special decorator enable this mechanism for subclasses as well enable this mechanism even for methods that are added to this class in runtime [Note: I'm using Python 3.2, so I'm fine if this relies on features added recently.] Here's my attempt: _methods_to_skip = {} def apply(decorator): def apply_decorator(cls): for method_name, method in get_all_instance_methods(cls): if (cls, method) in _methods_to_skip: continue if method_name[:2] == `__` and method_name[-2:] == `__`: continue cls.method_name = decorator(method) return apply_decorator def dont_decorate(method): _methods_to_skip.add((get_class_from_method(method), method)) return method Here are things I have problems with: how to implement get_all_instance_methods function not sure if my cls.method_name = decorator(method) line is correct how to do the same to any methods added to a class in runtime how to apply this to subclasses how to implement get_class_from_method

  • ios App Disclaimer

    - by Max
    I am writing an application for iPhone and had some questions regarding eula :- If I do not include any disclaimer/ eula in my app, then would Apple's standard EULA http://www.apple.com/legal/internet-services/itunes/appstore/dev/stdeula/ automatically apply to my app ? If I include a small disclaimer inside my application (as a popup on initial screen), then would Apple's EULA still cover my app ? I tried downloading few apps on my ipad and did not see Apple's standard EULA. So, where can I actually see the EULA before downloading something ?

  • C# Serialization Surrogate - Cannot access a disposed object

    - by crushhawk
    I have an image class (VisionImage) that is a black box to me. I'm attempting to serialize the image object to file using Serialization Surrogates as explained on this page. Below is my surrogate code. sealed class VisionImageSerializationSurrogate : ISerializationSurrogate { public void GetObjectData(Object obj, SerializationInfo info, StreamingContext context) { VisionImage image = (VisionImage)obj; byte[,] temp = image.ImageToArray().U8; info.AddValue("width", image.Width); info.AddValue("height", image.Height); info.AddValue("pixelvalues", temp, temp.GetType()); } public Object SetObjectData(Object obj, SerializationInfo info, StreamingContext context, ISurrogateSelector selector) { VisionImage image = (VisionImage)obj; Int32 width = info.GetInt32("width"); Int32 height = info.GetInt32("height"); byte[,] temp = new byte[height, width]; temp = (byte[,])info.GetValue("pixelvalues", temp.GetType()); PixelValue2D tempPixels = new PixelValue2D(temp); image.ArrayToImage(tempPixels); return image; } } I've stepped through it to write to binary. It seems to be working fine (file is getting bigger as the images are captured). I tried to test it read the file back in. The values read back in are correct as far as the "info" object is concerned. When I get to the line image.ArrayToImage(tempPixels); It throws the "Cannot access a disposed object" exception. Upon further inspection, the object and the resulting image are both marked as disposed. My code behind the form spawns an "acquisitionWorker" and runs the following code. void acquisitionWorker_LoadImages(object sender, DoWorkEventArgs e) { // This is the main function of the acquisition background worker thread. // Perform image processing here instead of the UI thread to avoid a // sluggish or unresponsive UI. BackgroundWorker worker = (BackgroundWorker)sender; try { uint bufferNumber = 0; // Loop until we tell the thread to cancel or we get an error. When this // function completes the acquisitionWorker_RunWorkerCompleted method will // be called. while (!worker.CancellationPending) { VisionImage savedImage = (VisionImage) formatter.Deserialize(fs); CommonAlgorithms.Copy(savedImage, imageViewer.Image); // Update the UI by calling ReportProgress on the background worker. // This will call the acquisition_ProgressChanged method in the UI // thread, where it is safe to update UI elements. Do not update UI // elements directly in this thread as doing so could result in a // deadlock. worker.ReportProgress(0, bufferNumber); bufferNumber++; } } catch (ImaqException ex) { // If an error occurs and the background worker thread is not being // cancelled, then pass the exception along in the result so that // it can be handled in the acquisition_RunWorkerCompleted method. if (!worker.CancellationPending) e.Result = ex; } } What am I missing here? Why would the object be immediately disposed?

  • Can I use the browser's word-wrapping from JavaScript?

    - by Max
    I have some text in a div. It can be any Unicode text under the sun, including Chinese, Japanese, and Korean. Now, I need to take this text and word-wrap it in JavaScript in some efficient but correct manner. (Because I need to make each line start with "" in a textarea.) Browsers have an implementation of the Unicode Word Wrap algorithm, as is evidenced by word-wrapping Unicode text in a with CSS. (At least, Firefox has such an algorithm, and I suspect other browsers do as well.) What I need is some way for JavaScript to use the same word-wrapping algorithm, so that I can properly wrap and then "quote" Unicode text. Is there any way for JavaScript to use the browser's word-wrapping algorithm, or to know where text has been line-broken in a div or any other element?

  • Finding the median of the merged array of two sorted arrays in O(logN)?

    - by user176517
    Refering to the solution present at MIT handout I have tried to figure out the solution myself but have got stuck and I believe I need help to understand the following points. In the function header used in the solution MEDIAN -SEARCH (A[1 . . l], B[1 . . m], max(1,n/2 - m), min(l, n/2)) I do not understand the last two arguments why not simply 1, l why the max and min respectively. Thanking You.

  • Keeping floated divs inline

    - by Elliott
    I'm having trouble getting my layout working correctly, I have a main div and a sidebar div these are both float: left if the screen size is resized or if its viewed on screen smaller that what I have designed on (1920x1080) then the sidebar div drops below the main content. I tried placing a wrapper around each div, but this has no effect. <div id="header"> [Header] </div> <div id="content"> [Content] </div> <div id="sideBar"> [SideBar] </div> <div id="footer"> [Footer] </div> body { width: 100%; color: #000000; background-color: #000000; margin: 0; padding: 0; } #header { width: 100%; height: 110px; background-color: #336699; color: #FFFFFF; margin: 0px; padding: 0px; } #content { float: left; margin-left: 50px; width: 70%; height: 700px; margin-top: 40px; padding: 30px; background-color: #FFFFFF; margin-bottom: 40px; } #sideBar { float: left; margin-left: 50px; width: 15%; height: 400px; margin-top: 40px; padding: 30px; background-color: #FFFFFF; } #footer { width: 100%; height: 80px; background-color: #174555; margin: 0px; padding: 0px; color: #ffffff; clear: both; } Basicly both div's should resize until a certain size is reached, then scrolling should be enabled. I'm pretty sure I have done something simple wrong but i'm not much of a design person. Example can be shown here : Link Thanks for any advice :)

  • Which class should store the lookup table?

    - by max
    The world contains agents at different locations, with only a single agent at any location. Each agent knows where he's at, but I also need to quickly check if there's an agent at a given location. Hence, I also maintain a map from locations to agents. I have a problem deciding where this map belongs to: class World, class Agent (as a class attribute) or elsewhere. In the following I put the lookup table, agent_locations, in class World. But now agents have to call world.update_agent_location every time they move. This is very annoying; what if I decide later to track other things about the agents, apart from their locations - would I need to add calls back to the world object all across the Agent code? class World: def __init__(self, n_agents): # ... self.agents = {} self.agent_locations = {} for id in range(n_agents): x, y = self.find_location() agent = Agent(self,x,y) self.agents.append(agent) self.agent_locations[x,y] = agent def update_agent_location(self, agent, x, y): del self.agent_locations[agent.x, agent.y] self.agent_locations[x, y] = agent def update(self): # next step in the simulation for agent in self.agents: agent.update() # next step for this agent # ... class Agent: def __init__(self, world, x, y): self.world = world self.x, self.y = x, y def move(self, x1, y1): self.world.update_agent_location(self, x1, y1) self.x, self.y = x1, y1 def update(): # find a good location that is not occupied and move there for x, y in self.valid_locations(): if not self.location_is_good(x, y): continue if self.world.agent_locations[x, y]: # location occupied continue self.move(x, y) I can instead put agent_locations in class Agent as a class attribute. But that only works when I have a single World object. If I later decide to instantiate multiple World objects, the lookup tables would need to be world-specific. I am sure there's a better solution... EDIT: I added a few lines to the code to show how agent_locations is used. Note that it's only used from inside Agent objects, but I don't know if that would remain the case forever.

  • async_write/async_read problems while trying to implement question-answer logic

    - by Max
    Good day. I'm trying to implement a question - answer logic using boost::asio. On the Client I have: void Send_Message() { .... boost::asio::async_write(server_socket, boost::asio::buffer(&Message, sizeof(Message)), boost::bind(&Client::Handle_Write_Message, this, boost::asio::placeholders::error)); .... } void Handle_Write_Message(const boost::system::error_code& error) { .... std::cout << "Message was sent.\n"; .... boost::asio::async_read(server_socket_,boost::asio::buffer(&Message, sizeof(Message)), boost::bind(&Client::Handle_Read_Message, this, boost::asio::placeholders::error)); .... } void Handle_Read_Message(const boost::system::error_code& error) { .... std::cout << "I have a new message.\n"; .... } And on the Server i have the "same - logic" code: void Read_Message() { .... boost::asio::async_read(client_socket, boost::asio::buffer(&Message, sizeof(Message)), boost::bind(&Server::Handle_Read_Message, this, boost::asio::placeholders::error)); .... } void Handle_Read_Message(const boost::system::error_code& error) { .... std::cout << "I have a new message.\n"; .... boost::asio::async_write(client_socket_,boost::asio::buffer(&Message, sizeof(Message)), boost::bind(&Server::Handle_Write_Message, this, boost::asio::placeholders::error)); .... } void Handle_Write_Message(const boost::system::error_code& error) { .... std::cout << "Message was sent back.\n"; .... } Message it's just a structure. And the output on the Client is: Message was sent. Output on the Server is: I have a new message. And that's all. After this both programs are still working but nothing happens. I tried to implement code like: if (!error) { .... } else { // close sockets and etc. } But there are no errors in reading or writing. Both programs are just running normally, but doesn't interact with each other. This code is quite obvious but i can't understand why it's not working. Thanks in advance for any advice.

  • Adobe Air: Read and Write MP3 or JPG from local directory and switch bytes

    - by Max
    I would like to make my local jpg and mp3 files kind of unreadable (without encoding) by just putting the first 100 bytes from the beginning of the file to the end and then saving the file with a .dat extension. I know I have to use the byte array but can't get it work. I would also need then a small function to read that file and put the 100bytes back to the front so that I can play/display the file. It would be great if you could post the whole function because I am quite new to Air so that I fully understand. Thank You!!!!

  • Which external DSLs do you like to use?

    - by Max Toro
    The reason I'm asking is because right now there seems to be tendency to make DSLs internal. One example is LINQ in C# and VB. You can use it against in-memory objects, or you can use it as a replacement of SQL or other external DSL. Another example is HTML5 vs XHTML2. XHTML2 supported decentralized extensibility through namespaces, in other words you embed external DSL code (XForms, SVG, MathML, etc.) in your XHTML code. Sadly HTML5 doesn't seem to have such mechanism, instead new features are internal (e.g. <canvas> instead of SVG). I'd like to know what other developers think about this. Do you like using external DSLs ? Which ones ? If not, why ?

  • How to determine which cells in a grid intersect with a given triangle?

    - by Ray Dey
    I'm currently writing a 2D AI simulation, but I'm not completely certain how to check whether the position of an agent is within the field of view of another. Currently, my world partitioning is simple cell-space partitioning (a grid). I want to use a triangle to represent the field of view, but how can I calculate the cells that intersect with the triangle? Similar to this picture: The red areas are the cells I want to calculate, by checking whether the triangle intersects those cells. Thanks in advance. EDIT: Just to add to the confusion (or perhaps even make it easier). Each cell has a min and max vector where the min is the bottom left corner and the max is the top right corner.

  • POSIX Threads and signal masks

    - by Max
    Is there a way to change the signal mask of a thread from another thread? I am supposed to write a multithreaded C application that doesn't use mutex, semaphores and condition variables, only signals. So it would look like something like this: The main Thread sends SIGUSR1 to its process and and one of the 2 threads (not including the main thread), will respond to the signal and block SIGUSR1 from the sigmask and sleep. Then the main thread sends SIGUSR1 again, the other thread will respond, block SIGUSR1 from its sigmask, unblock SIGUSR1 from the other threads sigmask, so it will respond to SIGUSR1 again. So essentially whenever the main thread sends SIGUSR1 the two other threads swap between each other. Can somebody help?

  • Is there a way to force lubuntu screen resolution?

    - by za1
    I have a Dell Inspiron 4000, 900 Mhz Pentium III, 192 MB RAM,10.1 GB disk running Lubuntu 12.04. When I start the computer, and I check the display resolution, Monitor Settings claims that the max resolution is 1024x768. I then connected another monitor I had lying around, rebooted, and now the laptop monitor looks normal,and monitor settings claims that 1280x1024 is the max resolution (it is) and the other monitor doesn't turn on. (black screen) The external monitor is not broken. Is there a way to, without the external monitor, force the laptop monitor resolution to 1280x1024? (The following is another question) - How can you run commands automatically at startup? Specifically "xinput 18 118 0" (without quotes) The first question is important, I can live with typing the second one at every boot. Thanks

  • Spring 3 - Theme with separate JSP

    - by Max
    Hi, I'm trying to rewrite some Spring 1.2 code to Spring 3.0 one. Currently I'm stuck with JSP resolved by URL problem. Application uses separate JSP files with different layouts for serving the same model from the same controller. The JSP is switched using interceptor, that intercepts the url and changes the view. For example: /design_one/mypage.htm -> MyPageController -> /design_one/mypage.jsp /design_two/mypage.htm -> MyPageController -> /design_two/mypage.jsp Is there a way to make same or similar functionality using something better than raw interceptors?

  • Incorrect output on changing sequence of declarations

    - by max
    Writing C++ code to implement Sutherland-Hodgeman polygon clipping. This order of declaration of these 2 statements gives correct output, reverse does not. int numberOfVertices = 5; Point pointList[] = { {50,50}, {200,300}, {310,110}, {130,90}, {70,40} }; I am passing the polygon vertex set to clippers in order - LEFT, RIGHT, TOP, BOTTOM. The exact error which comes when the declarations are reversed is that the bottom clipper, produces an empty set of vertices so no polygon is displayed after clipping. Correct: Incorrent: Confirmed by outputting the number of vertices produced after each pass: Correct: Incorrect: What is the reason for this error?

  • Java multidimensional array and scanner novice Q

    - by Max
    I'm new to Java and trying to in essence implement a grid with a character, and if the user inputs 'w' 'a' 's' or 'd' the character moves up/down/left/right within the plane. I created a multidimensional array sized 10x10 public static String[][] grid = new String[10][10]; And then just used a for loop to print "*"s in a 10x10 grid, except for grid[a][b] which is equal to character "A" i.e. my thing to be moved around. That seemed to work alright, then I needed to detect the 'wasd' input from the user so I set up a: Scanner in = new Scanner (System.in); while (in.hasNext()) And I had then: String s = in.next(); char ch = s.charAt(0); switch (ch) but I couldn't make this work, and it wasn't because I didn't complete the "switch" statement, I did, I just see it void copying and pasting the entire thing. I'm sure its incredibly easy slight thing I am missing, can you please point it out for me?
